Abstract: FIELD: production of uncontaminated mixed oxide fuel rods for atomic engineering. 
     SUBSTANCE: proposed method involves manufacture of uncontaminated MOX fuel rods from pellets in shielding chamber. The latter is held at pressure lower than indoor atmospheric value. Pellets are charged in stacked condition into can provided in advance with first plug on one of its two ends. Various structural components, such as hold-down spring, are charged. Second plug is installed on other end of can and held in position by circular weld, in particular when it is inserted in mentioned can without clamp. Parts of mentioned can or respective rod are at least once inspected for contamination. Safety chamber is divided into certain number of adjacent compartments. Each compartment communicates with adjacent one through sealed passage for can. Some of such passages are relatively aligned to provide for can movement along its longitudinal axis. Cans being charged with pellets are introduced with their open end forward into first compartment through sealed passage or inlet opening of compartment. Cans are moved along axis between sequential compartments until their open end occurs in last compartment. In the latter can is charged with pellets and, if necessary, with various structural members other than hold-down spring through its open end. Upon completion of charging can is partially pulled out along axis to transfer its open end to preceding compartment. In the latter can is at least partially cleaned and checked for probable contamination by pellets in the course of their charging or by atmosphere of last compartment. After that cans are moved to admit their open end to next compartment. Hold-down spring is installed and second plug is fitted in open end within this compartment. Then other required operations are made in this compartment or in another one involving additional movement of can. Parts of rod contaminated in last compartments are checked for condition and potentially decontaminated, as required, in first or second compartment. Rod is removed from first compartment or is crosswise displaced to other shielding chamber through first compartment that joins shielding chambers together. The degree of contamination stepwise changes between different compartments starting from no or negligible dirt in first compartment up to heavy contamination in last one. Gas supplied to these compartments is chosen from group incorporating air, nitrogen, helium, argon, and vacuum. Pressure within compartment is varied in steps to control leakage starting from high pressure in first compartment down to lowest pressure in the last one. In addition, device is proposed for producing uncontaminated MOX fuel rods. 
     EFFECT: enhanced safety for personnel engaged in manufacture of mixed oxide fuel rods.

Abstract: FIELD: medicine, psychiatry. 
     SUBSTANCE: it is necessary to carry out 6-8 courses of complex rehabilitation per 100 studies/each. Moreover, one should apply 3 types of studies: psycho-pedagogical rehabilitation, adaptive-physical rehabilitation and social-vocal rehabilitation. During the studies on psycho-pedagogical rehabilitation it is necessary to elaborate stress-resistance due to multiple repetition of stress loadings which become higher and higher from study to study to fulfill their psychocorrection. In the course of adaptive-physical rehabilitation it is important to fulfill deep muscular stretching and for this purpose it is necessary to perform gymnastic exercise called "piked seat" in static mode. At every study one should increase the duration of exercise implementation. Starting since the 10 th  study in the course of exercise it is necessary to make additional external loading onto a patient's back. Moreover, the weight of loading should be increased from study to study to achieve gradually the weight being equal to the half of a patient's body weight. During the studies on social-vocal rehabilitation it is necessary at first to activate the brain due to stimulating auditory and vocal areas. Moreover, for stimulating auditory area of the brain one should affect a patient's hearing with prolonged and/or loud sounds, and for stimulating vocal area of the brain a patient should be suggested to fulfill dosed vocal loadings as prolonged and/or loud pronunciation of sounds. The innovation enables to obtain stable and prolonged remission of the disease. 
     EFFECT: higher efficiency of therapy.
